Title: Magnetic storage device utilized in positioning amplitude of data signal
Inventor: TOYAMA HISAO
IPC: G11B21/10
Filed: 1987-10-21
Abstract: PURPOSE:To control closed loop positioning in a short time by periodically storing the output of an amplitude detector for positioning a magnetic head in the center of a track and periodically instructing a positioning part of the direction of a fine adjustment so that the output is maximum. CONSTITUTION:When the center 33 of the magnetic head 5 is in a position 21, it is finely adjusted to a position 22, and the amplitudes of a data signal in respective positions 21 and 22 are compared. Since the amplitude of the data signal in the position 22 is larger, the magnetic head 5 is finely adjusted in a same direction further, and similar comparison and fine adjustment are repeated in respective positions 23-25 and the center reaches a position 26. Next, it is finely adjusted to a position 27 and the amplitudes of the data signal in respective positions 26 and 27 are compared. Since the amplitude of the data signal in the position 27 is smaller, the magnetic head is finely adjusted in an opposite direction and it returns to the position 26. When a distance which is finely adjusted once is sufficiently minimized, the magnetic head 5 is positioned in a narrow range sandwiching the center 32 of the track. Thus, the head is accurately positioned.

Abstract: PURPOSE:To make it possible to mince meat without any waste by designing the subject that a squeeze-out ring is coupled with the periphery of a screw shaft in a storage cylinder to enable the ring to move in the shaft core direction of the screw shaft. CONSTITUTION:A squeeze-out ring 10 is in a rotatable condition with a screw shaft 8, so that the ring rotates at a position facing a through hole 21. If the feed of meat is almost completed, an engagement head part 23 is pushed out by the thrusting action of an operating member 22 to introduce the head part 23 into an engagement groove 25 in the ring 10, the squeeze-out ring 10 no longer rotates, leaving only the screw shaft 8 rotating. Further, the squeeze-out ring 10 moves in the shaft core direction due to a force applied in the shaft core direction to a female screw on the squeeze-out ring 10 by a screw blade 18. Subsequently, each guide rail 24 is introduces into each engagement groove 25 of the ring 10. Thus, the squeeze-out ring 10, guided by each guide rail 24, passes through the feed groove 19 of the screw blade 18 and thrusts out the remaining meat from the feed groove 19 to the tip of the storage cylinder 5.

Title: Vehicular lamp
Inventor: SHIDA HIROSHI
IPC: F21Y101/00
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent the edge of a bulb hole in a reflector made from a polycarbonate resin from being deformed by heat transferred from a bulb via a metallic bulb base when the bulb is turned on, in a vehicular fog lamp in which the bulb base is inserted into the bulb hole in the reflector. SOLUTION: Insertion of a bulb base 24 into a bulb hole 14a is performed via an adapter 26 made of polyamide resin. When a bulb 16 is turned on, heaty transmitted from the bulb 16 to the bulb base 24 achieves temperatures as high as about 160 deg.C, while the adapter 26 intervenes to prevent direct transmission of the heat to a reflector 14. Because the polyamide resin has a heat- resisting temperature of about 190 deg.C, deformation of the adapter 26 itself is prevented, and because resin materials including polyamide resins generally have a low heat conductivity, the temperature of the heat transmitted to the reflector 14 is reduced to or below the heat-resisting temperature of a polycarbonate resin.

IPC: H04B17/00
Filed: 1990-10-04
Abstract: PURPOSE:To attain quick error detection in response to an error rate without increasing a circuit scale by making a timer monitoring period variable. CONSTITUTION:An error counting circuit 12 counts the output pulse of an error detection circuit 10 and outputs an output pulse to a protective stage number setting circuit 14 when the count is a set value or above. When the count of the error counting circuit 12 reaches the set count and the circuit 12 generates the output pulse, the output resets a time monitoring circuit 16 via a resetting circuit 18 to restart the counting. The setting circuit 14 is reset when the time monitoring circuit 16 gives a reset pulse to the error counting circuit 12 at a scheduled time. As an error rate is increased, the output of an error detection signal is faster to attain quick error detection.

Title: Toner for pressure sensitive adhesive sheet
Inventor: HARADA YOSHIAKI
IPC: G03G9/08
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain a pressure sensitive adhesive sheet that a toner image as confidential information on the surface of the folded sheet is not transferred to the counter face and that the same adhesive face without contamination can be kept after peeled as during printing, by using toner particles with deposition of inorg. fine particles on the surface. SOLUTION: This toner is prepared by first mixing specified proportions of a binder resin and coloring agent or the like, melting, kneading, pulverizing, classifying and if required, heat treating to produce color fine particles. Then inorg. fine particles are deposited on the surfaces of the color fine particles by spraying inorg. fine particles to the color fine particles by a mixing machine. As for the inorg. fine particles, iron oxide and titanium oxide are preferably used because these particles are easily and uniformly deposited on the surfaces of the color fine particles. The average particle size of the inorg. fine particles is preferably 0.1 to 0.6 μm. If it is less than 0.1 μm, the effect to prevent the toner from transferring to the counter face of the pressure-sensitive sheet is not enough obtd.  If the size is larger than 0.6 μm, developing property of the toner decreases, which easily causes problems of the image quality of a printed image.

Abstract: PURPOSE:To enable an acceleration detection device to output an acceleration signal accurately without vibrating it by a method wherein a board mounted with the acceleration detection device which detects an acceleration in a certain direction is rotated by a rotating device. CONSTITUTION:A semiconductor acceleration detection device 1 is rotated by a rotating device 7, and when an angle theta of rotation is set to 90 deg., an acceleration detected by the detection device 1 is equal to 0G (0m/S<2>) which is the product of an applied gravitational acceleration 6 and the cosine of the angle 1 of rotation of a board 2 to a horizontal direction 10. When the device 1 is further rotated to make the rotation angle theta equal to 180 deg., a detected acceleration 9 is equal to -1G. Therefore, an acceleration ranging from -1G to +1G can be applied to the semiconductor acceleration detection device 1. As mentioned above, a semiconductor acceleration detection device is rotated, whereby an acceleration ranging from -1G to +1G can be applied, so that an output characteristic of high accuracy can be obtained for the acceleration applied to the acceleration detection device.
